* Testing conducted by Apple in August 2016 using preproduction iPhone 7 units and software paired with preproduction iPhone 7 Smart Battery Case units and preproduction software. Video tests consisted of repeated playback of a 2‑hour 23‑minute movie purchased from the iTunes Store. Internet tests were conducted over 3G, 4G LTE and Wi‑Fi networks using a dedicated web server, browsing snapshot versions of 20 popular web pages and receiving mail once an hour. Talk time tests were conducted by placing a mobile phone call. All settings were default except Bluetooth was paired with headphones; Wi‑Fi was associated with a network for all but the Internet 3G and Internet 4G LTE tests; and the Wi‑Fi feature Ask to Join Networks and Auto‑Brightness were turned off. All battery claims depend on network configuration and many other factors; actual results will vary.
